Title: Improvements in abrasive products and methods of manufacturing them
IPC: C08L27/00
Filed: 1936-12-29
Abstract: Abrasive articles are prepared containing as the binding medium one or more polymerized vinyl compounds containing sufficient hydroxyl groups to be water-soluble or self-dispersible in water or the reaction product of such vinyl compounds with hardening or insolubilizing agents.  Suitable binding agents include polyvinyl alcohol, partially hydrolysed polyvinyl compounds, polymerized vinyl esters of hydroxy acids such as polyvinyl lactate, polyvinyl tartrate, chlorinated polyvinyl alcohol, and interpolymers of polyvinyl alcohol and vinyl methyl ether.  Suitable hardening agents include aldehydes such as benzaldehyde and formaldehyde, phenolic resins containing free aldehyde, tannic acid, chromic acid, chromium compounds, chlorine, bromine and sulphur.  Other water-soluble binders such as glue, methyl cellulose, polyvinyl methyl ether, polymerized acrylic compounds, sodium silicate, water-miscible phenol- or urea-aldehyde resins, or aqueous dispersions such as rubber latex may be used in admixture. Viscosity of solutions of the binder may be decreased by a peptizing agent such as the zinc chloride salt of phenyl hydrazine.  The abrasive articles may be abrasive grains adhering to a backing wherein either the glue or the top size is the vinyl compound.  In examples: (1) polyvinyl alcohol (derived by hydrolysis of polyvinyl acetate in solution in anhydrous methyl alcohol by means of anhydrous hydrogen chloride) dissolved in water with or without addition of glue is used as the adhesive and size layer in the manufacture of abrasive paper; (3) the polyvinyl alcohol used in example 1 is derived by hydrolysis of an acetone solution of polyvinyl acetate, which may have been interacted with acetaldehyde, by means of aqueous hydrochloric acid; (5) the polyvinyl alcohol used in example 1 may be esterified with lactic acid; (6) polyvinyl alcohol (prepared by treating a solution of polyvinyl acetate in anhydrous methanol with a solution of sodium in methanol) is dissolved in water and mixed with a liquid phenol-formaldehyde condensation product, an ammonia solution of an alkyd resin, aqueous solution of a urea-aldehyde initial condensate, solutions of solid phenolic resins, drying oil-modified resins, or liquid alkyd resin and the product used as adhesive and size in manufacture of abrasive cloth; (7) alumina grains are stuck to a wheel prepared from laminated muslin (using polyvinyl alcohol as an adhesive) by means of aqueous polyvinyl alcohol; (8) a paste of alumina grains and a little aqueous polyvinyl alcohol is applied to the laminated wheel described in example 7; (a) alumina grains are mixed with aqueous polyvinyl alcohol and after drying the mass is pressed; (10) alumina grains are mixed with an aqueous solution of polyvinyl alcohol containing a liquid heat - reactive phenolic condensation product and the product is mixed with powdered A-stage phenolic resin and then moulded.

Title: Improvements in or relating to stencil printing cylinders
IPC: B41C1/14
Filed: 1954-12-16
Abstract: 756,315. Stencils. BARROS, A. J. C. DE O. Dec. 16, 1954 [Sept. 24, 1954], No. 36438/54. Class 100 (2). A cylindrical stencil screen is formed by coating a flat, metallic mesh screen on one side only with an impervious material, removing the coating according to the desired design, bending the screen into a cylinder and plating the exposed parts of the cylinder in an electrolytic bath so that the mesh is made rigid by the metallic deposit. A very thin metallic deposit is also formed over the impervious coating. The coating 12, Fig. 7, is photo-sensitive so that the design can be formed by exposure to light, developing and washing out. The screen is bent round with the coating inside and welded along the seam 16, Fig. 3. The ends of the screen are soldered to rings 18. For the plating process metal end discs 24, Fig. 5, are inserted in the rings 18 and a shaft 44, e.g. of stainless steel, is passed through the discs 24 insulated therefrom by bushes 40. The ends of the shaft 44 are supported on bearings 48, 50 in the bath and a gear drive on one end enables the cylinder to be rotated slowly during the plating process. Spring brushes 32 bearing on cylindrical bosses 26 of the discs 24 connect the cylinder with one pole of an electric supply and anodes 54, 55 suspended from cross pieces 52, 53 are connected to the other pole. The anodes, e.g. of copper, are of plate form and curved so as to be spaced about the surface of the cylinder. The bath may be a copper sulphate and sulphuric acid solution. After the plating process the wires of the screen 10 are locked together where they cross and thickened as shown at 64 in Fig. 7. The cylinder is thereby rendered rigid and the impervious coating is also strengthened by a thin metallic deposit thereon. Alternatively, the screen may be bent so that the impervious coating is outside, the anode then being arranged inside the cylinder, for instance it may be formed by the shaft 44.

Title: Improvements in or relating to disc brakes
Inventor: STIRLING WALTER ROBERT
IPC: F16D65/095
Filed: 1957-11-22
Abstract: 867,785. Disc brakes. AUTOMOTIVE PRODUCTS CO. Ltd. Nov. 24, 1958 [Nov. 22, 1957], No. 36523/57. Class 103 (1). In a spot-type disc brake, pads of friction material 22 are urged against the surfaces of the disc 10 by pistons 23 operating in opposed hydraulic cylinders one on each side of the split caliper housing 12, 13 such that the pistons have their axis substantially aligned with the centres of the pads and the pistons act on the backing plates 21 through protuberances 9 which are formed by the unrelieved rim portion 24 of the pistons such that the protuberances are at positions offset, from the centres of the pistons towards the trailing edges of the pads to increase pressure at the trailing edges of the pads. Owing to the fact that the pistons 23 are relieved at 26 they tend to press the trailing edges of the pads 22 more firmly against the disc 10 than the leading ends and this has been found to reduce or eliminate squeaking or squealing of the brakes. The backing plates 21 are each provided at their ends with protuberances 28 having convex arcuate edges; the protuberances fitting into arcuate notches 29 in the projections 15 which form the end walls of the recesses 16 and providing the main guiding means for locating the backing plate 21 in the recesses 16. Other means may be employed for producing the different pressures on the leading and trailing edges of the pads. For example, the pistons 23 may have flat ends and each backing plate 21 may have on its rear surface a protuberance 41 (Fig. 4), in a position offset from the centre towards the trailing edge of the pad mounted on the backing plate, so as to be engaged by the part of the periphery of the piston which lies nearest to the trailing edge. The protuberance 41 may be conveniently formed as shown in Fig. 4 by welding to the backing plate a small strip of metal having a thickness of, for example, 15 thousandths of an inch.

Abstract: 1,224,013. Cheese product. H. J. PALMER. 7 Aug., 1969 [31 July, 1968], No. 36614/68. Heading A2B. Hard cheese, such as cheddar, is mechanically converted into a finely divided state and thereafter subjected to freezing at such a temperature that the moisture content of the cheese is converted into ice crystals. The product may be employed in place of grated cheese. In one form the finely divided cheese is in the form of a mouldable mass, which is wrapped or inserted in an air impermeable envelope, for example a tube, in a somewhat compressed state, and subjected to freezing. The product may be stored refrigerated or not, and used as a paste. In another form, the finely divided cheese is in the form of discrete particles or flakes, and is rapidly frozen. The product is stored refrigerated until required for use.
